Abstract

This paper introduces a new technique for reducing the compulsory misses of software-managed TLBs by prefetching necessary TLB entries before being used. This technique is not inherently limited to specific application. The key of this scheme is to perform the prefetch operations to update the TLB entries before first accesses so that TLB misses can be avoided. For the identifications of the prefetch pages, the new classification is introduced, which is based on the view of an object code execution. Then, the algorithm and the implementation technique are described. Using a quantitative analysis, the proposed scheme is evaluated to prove that it is a useful technique for the performance enhancement of the S/W managed TLBs. In addition, it is discussed that reducing the miss rate by the prefetch scheme reduces the total miss penalty and bus traffics in S/W-managed TLBs.
